OK, _WHY_ did you do this, then?

Unless you're intending or needing to upgrade service from (say) 100 to
200A in view of an impending remodeling or other anticipated increased
loading or also replacing a 2-wire system w/ 3, what's the point?

Possibly because they aren't blowing fuses since someone has already
overfused the old panel and it's a fire waiting to happen? A single 30A
edison base fuse feeding several 14ga circuits isn't exactly uncommon on
some old panels.
